lately, I'm working on projects that are distributed through many directories on different drives. I really like the directory/navigation tabs (Ordner-Tabs/Register in the german translation), and I lock the ones I need to go back to regularily.
However, everytime I go to a locked tab and navigate up or down the directory tree, I get a new tab, and my tabs-bar gets really messed with those tabs.
Allowing 'cd' for the locked tabs does not help much, either: when I use CTRL+D or other navigation tools, I may change the directory in the current tab to a place that the tab's name as no longer any relation with.
My suggestion: introduce a global configuration flag to set the following behaviour:

Whenever any navigation activity would open a new tab in the current TC version, do the following if the option is set: look for a non-locked tab; if one is found, activate that tab and do the navigation there; otherwise: open a new tab.
I hope that this is a minor change at one dedicated place in the code, and it would tremendously aid my work by not messing the tab bar any longer.
Thanks for considering!
